To all whom it may concern:

Be itknown that we, HARRY S. F LGER and TOBEY Ross, citizens of the United States of America, and residents of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Self-Liking Stamps.

)ur invention relates to the type of self inking time stamp in which the inking apparatus is normally free from the time indicafor its object improvements in Fig.2 isa side elevation; Fig. 3 is a plan, the upper parts being removed by section on line 33 of Fig.1; Fig. 4 isa section on line 44 of Fig. 1; F ig. 5 is a section on line 5-5 of Fig. 1,

the clock being shown in plan;

The central part of the guides 21 are cut awayto form slots 23, and the upper ends of the slots of the legs of the slide 22 are slotted, and the .metal from the slots is bent outward to form lips 25 which project through the slots 23. Mounted on the lips 25 are rubber cushions 26 which are adapted to come in contact with the lips'24 to limit the upward movement of the slide in the guides.

of the slide 22 by brackets 27 secured to the inner faces of said legs and to the posts 11 of clock 10. Also secured to the posts 11 is a bridge 28, the central portion of which serves as the lower guide for a stem 29 of handle 30, the upper guide being an opening in the central part of the slide 22 similar to the opening in the bridge 28 which serves as the lower guide. It will be evident that the handle 30 and its stem 29 have a sliding movement with respect to the slide 22.

Pivoted at 31 (Figs. 2 and 4) on each leg of the slide 22 are bell crank levers 32, the laterally projecting arms of which are connected together by a rod 33. Secured to the lower end of-the stem 29 is an arm 34 which spect to the slide 22, that movement causes the arms 32 to swing on their pivots 31.

. The bell crank arms 32 are provided with lips 36 (Fig. 1) arranged to support and guide the sliding rods 37,. which rods project through slots 43 in the brackets 27 (Fig. 3) and carry at their lower ends an inking roller 38 adapt'ed to travel across the face of the die l213-l415 when said arms swing on their pivots 31. Springs 39 and adjustable nuts 40 on rods 37 serve to hold the roller against the die during such movement. The ends of the shaft 41 of roller 38 preferably progect into slots 42 in the side plates-16 and 17. (Fig. 2). )Vhen the roller ends of the shaft 41 engage hold the roller (Fig. 6). a I

Springs 44 (Fig. 1) mounted on the pivots of the bell cranks 32 serve to swing the rods 37 so as, to normally elevate the and hold the roller 38 20 on rod 19. WVhen the upper edge 38clear of the against the rubber .the handle is manually depressed, the roller I 38. traverses the face of the die and has its swing ng movement brought to a stop by a contact withthe upper part of the vertical ink pad 45 removably supported on the tie plate 18. As the sliding of the stem 29 with respect to the slide 22 is stopped by contact between the roller 38 and pad 45, further depression of the handle moves the slide, and parts carried thereby, downward until the die strikes at the printing point.

In this downward movement the roller 38 Vstopp ng lugs 2 1; Further upward. movement by the handle is then under the itOtlOIl the'shaft 46 is 7' '7 driver slot 51 in the ratchet wheel e9 serves 46 to adjust traverses the face of the pad 15 and-becomes inked.

The dog 50 holds the adjustment made.

The pad 45 is contained in a box 52, the

lower edge of whichrests onthe lower lip of the tie plate 18. Secured to the upper edge. of the box 52 is a handle53 made in the form of a clamping spring, the free I end of which engages a notch 54: in the tie V the path of "depressed plate 18. 'The construction provides an easy means for removing the pad for inkmg purposes.

In ordicatch 56,'and in the slide nary operation there is no engagement between the catch and the pin. But if the apparatus be turnedupside down (Fig.9) so that it may rest with thehandle- 30 on the table or desk, the heavy end of the gravity catch will move the hook the. pin.
